How do they move? • What makes glaciers unique is their ability to move… • Due to their sheer mass, glaciers, under their own weight, flow down hill like very slow rivers of snow…. Striations - ____________________________________________________________________________________ ____________________________________________________________________________________ Different Kinds of Glaciers,,,, a) Valley (Alpine) Glaciers - ___________________________________________________________ ___________________________________________________________ b) Continental Glaciers - _______________________________________________________________ ________________________________________________________________ Name __________________________________________________ Date_____________________________ Valley Glacier Features: ________________________ - eroded glacial valleys tend to be "U" shaped in cross section. ______________________– bowl shaped depression scooped out at the head of the glacier. ________________________ – 3 or more cirques eroding (attacking) one peak. _____________________ - sharp ridge between 2 glacial valleys. Continental Glacier Features: ____________________ - circular depressions made by large pieces of melting ice. ____________________ - mounds of sediment deposited along the front of a melting glacier. ____________________ - long, winding ridge of material deposited by a stream below the glacier. Transported Material: ______________________- unsorted material carried with in the glacier produced by scour and abrasion . ________________________- material carried along the sides of the glacier (valley walls). ________________________- when two glaciers valleys meet, it’s the material in the middle. ________________________- marks the end or furthest advance of the glacier. ________________________- sediments deposited by melt water at the end of a glacier. ________________________- large rocks carried, then deposited by the glacier.
